PRINCIPLE OF OPERATION
Fan Set is a device used to supply and exhaust air. The engine, mounted in the housing, drives the impeller located
inside. The fan, after accelerating to the dedicated rotational speed, is able to force the flow through the air handling
unit. Special designed 7 backward-curved blades in frame redirect exhaust of air at 90 degrees so that the centrifugal
effect increases the pressure and power of the fan. Ventilating cone of dedicated diameter is mounted on the opposite
side. All parts are made of high quality materials:
Figure 4 - airflow pattern threw the fan section and fan impeller
Please be advised that mounting multiple Fan Sets in a single configuration needs to be caried out with proper
dimensional requirements. For the outlet side the proper clearance [A] is equal to 1.2 x impeller diameter
(1.2 x D). The recommended clearance at the inlet side [B] should be equal to half of the impeller diameter
(D/2).

Additional information printed on the name plate is as follows:
•Serial number –a unique number given for each fan product to allow easy production, transportation, delivery and
operation traceability.
•Quality control date - date in the DD/MM/YYYY format of the quality control of the final product carried out in the

AIR VOLUME MEASUREMENT
Fan Set are equipped with the inlet cone. Air volume measuring device with circular lead is placed on the inlet side of
the cone. Measuring device is positioned perpendicularly to the air flow direction . With the assistance of the measuring
device it is possible to control the air volume depending on the difference in pressure between the static pressure at the
inlet cone and the static pressure on the inlet area. This sensor cannot measure the dynamic pressure in the inlet area.
While Fan Set is tested it is possible to regulate air volume.
The air volume is calculated according to the following formula.

Difference between actual airflow value and value calculated
with k-factor should be less than 10%. K-factor is determined by
comparative measurement on a standard test rig under standard
test conditions –reference density 1,2 kg/m3. Airflow can be
converted to different density of air using below formula:

CONNECTION AND DIAGRAMS
To perform the correct setup, please refer to the following diagrams representing possible ways of motor
connection. Installation and connection can be done by qualified personnel only. Failure in performing in any
of this operations may result in risk of fatal injury, electric shock, incorrect mounting or product damage.
Do not open or disassemble the motor while power supply is connected to the device. It may result in fatal
injury caused by electric shock. If it is necessary to open the motor, wait at least 5 minutes after disconnecting
from the power supply.
Electric system and equipment available at the contractor site must be operated and maintained in
accordance with the electro-technical regulations.
Notes on proper installation:
•Use fuses at power line
•Check the wires condition before operating. Make
sure that there are no short circuits.
•Use cables fulfilling the voltage, current, load and
insulation installation requirements.
•Use only high quality hard wire or fiber copper
wire with ferrule.
•Use shield cable.
•Make sure that motor label plate specification
matches the operating supply voltage. Use cables
that are adapted to work with the desired current.
Connection instructions:
1. Remove the Top cover of the terminal strips.
2. Fasten the control and main power wires by screwing them to the connector.
3. Check all connections again and carefully replace the Top cover.
4. Connect the Power supply voltage.

COMMUNICATION
The motors can be controlled via an analog connection and using the Modbus protocol.
The EC169W-B190 / 44P1-05 engine can only be controlled using the Modbus protocol. The 092 and 102 series motors
can be controlled in both ways. The parameters and control methods are presented below. The default manufacture
preset is set to analog 0-10V.
3.4.1 ANALOG INPUT
AN1: Analogue input 1 –Electronics can be controlled by external analogue input voltage 0-10 VDC. Electronics controls
speed linear from RPM min to RPM max. Maximal or minimal speed is defined as input voltage 9V ± 3%.
AN1Min parameter can be set to the desired minimum setpoint. AN1Max parameter can be set to the desired maximum
setpoint. AN1Min and AN1Max can be set from 0V to 10V.
By AN1Stop, stop threshold voltage can be set. If AN1Stop is 0 threshold voltage is disabled and motor will run with
minimal settable RPM. By setting AN1Stop higher than 0 motor will not run up to settable value.
For example if AN1min is set to 1,3V, AN1max is set to 9V and AN1stop is set to 0V controller works from 200 rpm to
1500 rpm and motor will run with minimal rpm. AN1 operates from 1,3V to 9V (AN1max > AN1min). If AN1stop is set to
1V then motor will not run below 1V. These examples show the charts below. (Figure 12)
Electrical parameters: Vinmax=12V, Zin=10kΩ, Resolution 10-bit, tolerance AN1±5%

3.4.2 MODBUS RTU
Electronics are equipped with Modbus RTU 485
communication. To connect controllers into
chain use only shielded cables. Shielded wires
for grounding connection between controllers
is necessary.
The MODBUS RTU protocol is based on the
built-in RS-485 (EIA-485) interface. RS-485 is a
two-wire bus-interface that allows multi-drop
network topology i.e. nodes can be connected
as a bus (daisy chain), or via drop cables from
a common trunk line.
Drives uses the two-wire system where the
communication between master and slave is
half duplex, i.e. it cannot transmit and receive at
the same time. Each signal uses one twisted
pair line —two wires twisted around
themselves. The signal on one wire is ideally the
exact opposite of the signal on the second wire. Since RS-485 is a multipoint communication system, all devices are
connected to the single twisted-pair cable. The Modbus RTU uses master/slave architecture, where each slave device
has its unique address and responds only to packets addressed to this device. The packets are generated by the master
(Controller), which periodically polls all connected slave devices. Data travels over the single line in both directions.
Multiple EC drives can be connected to a control (or master) using the RS-485 standardized interface. Maximal number
of EC Drives connected to the network is 32. Use parallel connections method to connect multiple frequency converters.

PROTECTIONS
3.5.1 THERMAL PROTECTION
The electronics is equipped with reducing thermal protection. This function is a temperature limiter which reduces the
output power, when temperature on the controller rises over 90֯C. In case in which temperature is still rising (over 105֯C)
the controller stops the motor. When temperature of the controller falls below 75֯C, the motor automatically restarts.
3.5.2 UNDER AND OVER VOLTAGE
The electronics are equipped with under and over voltage protection. Electronics shutdown when the main voltage is
not in the required range. See mechanical and electrical specification.
3.5.3 BLOCKED ROTOR PROTECTION
The electronics are equipped with blocked rotor protection when the rotor of motor is blocked or it is impossible to rotate
it. Electronics automatically retries 25 restarts, than a manual restart by disconnecting the power supply is required.
3.5.4 MOTOR PHASE FAIL/LOSE
The electronics are equipped with motor phase fail protection in event in which one of phase motors is damaged or
missing. In such case, electronics stops the motor immediately.
3.5.5 PHASE OVERCURRENT PROTECTION
The electronics are equipped with phase overcurrent protection. In this event electronics stops the motor immediately
and tries to perform restart automatically.
3.5.6 ROTOR FAILED ACCELERATION
The electronics are equipped with rotor failed acceleration protection hen the rotor is damaged or hardly rotates.
Electronic automatically retries to perform 25 restarts in 1second intervals. If the 25th restarts is still unsuccessful, then
manual restart by disconnecting the power supply is required.
Heating the controller over the maximal temperature is not allowed.
Above 105 oC electronics stops the motor, and restarts it again when the temperature of controller falls below 75 oC.
However, if the controller is overheating and motor was shutdown, disconnect the power supply (using safety switch)
and wait at least 20 minutes before performing any service tasks. In case of overheating of controller, the metal parts of
them are very hot and could cause serious damage to your skin.
If controller starts reducing output power during operation, this may be a reason of overheating. Ensure air flow through
the ribs/motor. Overheating problem appears in the case of installation of the controller in the space without the proper
air flow.
